Question

What is the best way to alter something based on the current date?

My goal is to dynamically change a message based on how close a specific date is. The objective is to update an element of a webpage to display "Renewal Unnecessary" when the date is more than 3 months away, "Renewal upcoming" when the date is less than 3 months away, and finally "Renewal Required!" when the date is just 1 month away. As of now, my code snippet looks like this:

if()
   {<hre>Renewal Required!</hre>}
else if()
   {<ha>Renewal upcoming</ha>}
else
   {<hg>Renewal Unnecessary</hg>}

I am struggling with determining the condition for this script to execute properly. For instance, the renewal date might be set for February 26th - is there a way to synchronize it with the computer's current date?

Answer №1

The Date.now function provides the current date in milliseconds format. To ensure accuracy, simply subtract the renewal_date by Date.now() and compare the result with the correct number of milliseconds.

Consider this approach to achieve the desired outcome, taking into account the current day of the month as well. Experience it live (click here).

var deadline = new Date(2014, 1, 2); //February 2, 2014 (January is Month 0)
var today = new Date();

var monthDiff = deadline.getMonth() - today.getMonth();

if (monthDiff < 3) {
  console.log('Deadline is in 3 months or less!');
}

if (monthDiff <= 1) {
  console.log('Deadline is in 1 month or less!'); 
}

In response to your query: There are multiple ways to accomplish this task - start with the basics. Here are two examples that may provide guidance.

var p = document.createElement('p');
p.textContent = 'Insert message here';
document.body.appendChild(p);

If the element already exists on the page:

var elem = document.getElementById('myElem');
elem.textContent = 'Insert message here';
